[Prior Art]

按，發光二極體（LED)的照明已廣泛應用在 日光燈、吸頂燈、探照燈、燈泡等燈具上均發揮 —定的效能；惟，發光二極體的發光是單方向射 出，因此對於手電筒、探照燈、吸頂燈、日光燈等 單方向射出的光源燈能夠較早被開發且應用不 錯’但如果欲將發光：極體應用設計成輻射狀發光 (廣角照明）的燈泡上’則在設計上要比傳統的發 光二極體燈具要更困難許多，且仍有許多需要克服 請參看帛5圖所*，係為傳統的發光二極體燈 泡設計’ ±要設有一燈座（5 〇 )，於一端設有電 路板（60)，在肖電路板（6〇)上以表面枯著（隨) 方式設有數顆發光二極體（7 〇 ),再設—球形燈 罩（圖中未示）於其上而形成一燈泡設計；請配合 參看第6、7圖所示，上述諸發光二極體（7 〇 j 之結構’係具有一傾斜的外環牆（7 1 )，在該外 201135152 環牆（7 1 )内則以螢光粉封膠（7 2 )封設有發 光二極體晶片（7 3 )，使得該發光二極體晶片（7 3 )發光後，能朝著前方並沿著外環牆（7丄）（7 1 0 )射出，惟此種結構在使用上具有如下之缺點： 1 ·由於發光二極體晶片（7 3 )向外發射的光線受 到周圍的外環牆（7 1 )所阻擋，故正常的投射 - 角度僅有120度以内；因此，此種燈泡無法得到 鲁 較廣角度的照明’是主要的缺點。 針對這個缺點，吾人可以第8圖及附件所示 的實際攝像圖來表示（附件攝像圖的左上角即為 習用的發光二極體燈泡光影攝像），如主要亮度 的第一光型分布線（C JL )及次級亮度的第二光 型为布線（C2)均落於燈座（5 〇)端面的水 平線（L〇)以上或附近，故在燈罩（8〇)的 下方周緣其實是十分暗淡的，造成照明的不足， Φ 是其主要的缺點。 2.其次，如第6圖所示，由於習用的發光二極體（7 〇)係為已完成封裝的零件（晶片），故需再將其 以SMT方式焊設在燈座（50)上的電路板 ◦)上’由於體積較大且需要作業空間，故使每一 發光二極體（7 〇 )間的距離（s )較大，則當欲 使用多顆的發光二極體（7 〇)時，除了佔用較大 的電路板（60)面積，同時散熱模組亦更大在 201135152 成本上較高’而產品體積亦更笨重為缺點。 【發明内容】 本發明之主要目的，係將燈座散熱模組的一端 設有電路板，同時該電路板上的高功率發光二極體 係以COB(即CHIP〇NB〇ARD)方式設於電路板 _ 上；另設一球形燈罩，係罩設於燈座散熱模組之發 光一極體上方；因此，使用本發明時，由於發光二 • 極體係以C0B(即CHIP ON BOARD)方式設於電路 板上，故發光二極體的發光角度接近18〇度，再加 上球形的燈罩内壁的特殊塗佈處理，能使燈泡所發 出光的角度可達270度以上；而在整體的亮度上， 該主要照明的光均可及於燈座端面的水平線以下， 使付燈泡的下半部周遭仍具有極佳的照明，為本發 明之特色。 本發明之設計，以發光的發光角度及均勻度來 • 說，是等同於習用的鎢絲燈泡及省電燈泡的輻射狀 發光效果’但由於本案係使用LED燈泡，故成本及 壽命均高，且更為環保、明亮，是本發明的主要優 點。 【實施方式】 為使貴審查委員能清楚了解本發明之内容，僅 以下列說明搭配圖式，說明如后： 請參看第1、2圖所示，本發明至少包含有： 一燈座散熱模組（i 〇 )，於一端設有電路板（2 201135152 ◦)，同時該電路板（2 0 )上至少設有一顆發光二 極體（3 0 )(但本發明之圖式以六顆為示意），該 發光二極體（3 0 )係以COB (即CHIP ON BOARD) 方式設於電路板（20)上。 請參看第5圖所示，由於發光二極體（3 〇) 係以COB(即CHIP ON BOARD)方式設於電路板（2 0 )上，故該發光二極體（3 〇 )的射角係幾乎直 φ 接由電路板（20)上向外擴散射出，一般幾乎可 達約180度的發光角度（㊀1 )。 上述第1、2圖所示的燈座散熱模組（1 〇)， 是用來吸收並傳導該發光二極體（3 〇 )所產生之 熱，並予導引消散。 一球形燈罩（4 0 )，係罩設於燈座散熱模組（1 0)之發光二極體（30)上方，該燈罩（4〇) 的内壁（4 0 〇 )係為球形的内面弧度，如第2、 • 3圖所示，當發光二極體（30)發出強烈的白光 時，能均勻的朝燈罩（40)的内壁（4〇〇)散 出，其中，發出之光線（L1)若係垂直或接近垂 直的角度投射於燈罩（40)的内壁（4〇〇)時， 即會穿過燈罩（4 0 )’若過於傾斜投射於燈罩（4 0 )的内壁（4 0 〇 )時，該光線（L 2 )即會在 燈罩（40)内持續反射，直至穿過燈罩（4〇)， 因此達到接近於傳統燈泡的全面光線投射。 另外，為使燈泡内部的光反射均勻，該燈罩（4 201135152 (η的内壁"〇〇)可塗佈有使光線均句的反射 材料’能得到更均勻的明亮度。 因此，使用本發明時，如第3、4圖所示，由 於本發明的發光二極體（3〇)係、以c〇b(即cmp ON BOARD)方式設於電路板（2 〇 )上故發光二 極體（3 0 )的發光角度接& 18〇《，再加上球形 的反射，能使燈泡 的燈罩（40)内壁（4〇〇According to the illumination of the LED (LED), it has been widely used in fluorescent lamps, ceiling lamps, searchlights, bulbs, etc.; however, the illumination of the LED is emitted in one direction, so for the flashlight, Single-direction light source lamps such as searchlights, ceiling lamps, and fluorescent lamps can be developed earlier and applied well. 'But if you want to illuminate: the polar body application is designed to be a fluorescent light (wide-angle illumination), the design is better than Traditional LED diodes are much more difficult, and there are still many things to overcome. Please refer to Figure 5 for the traditional LED bulb design. ± One lamp holder (5 〇) is required at one end. A circuit board (60) is provided, and a plurality of light-emitting diodes (7 〇) are provided on the swash board (6 〇) with a surface dry (and), and a spherical lamp cover (not shown) is disposed thereon. Forming a light bulb design on the top; please refer to Figures 6 and 7 for the above-mentioned light-emitting diodes (the structure of 7 〇j has a slanted outer ring wall (7 1 ), and the outer wall of 201135152 (7 1 ) is sealed with fluorescent powder 7 2) A light-emitting diode chip (73) is sealed so that the light-emitting diode chip (73) emits light toward the front and along the outer ring wall (7丄) (7 1 0). However, this structure has the following disadvantages in use: 1) Since the light emitted from the LED chip (7 3 ) is blocked by the surrounding outer ring wall (7 1 ), the normal projection-angle is only It is less than 120 degrees; therefore, this kind of bulb can't get the illumination of a wide angle. It is the main disadvantage. For this shortcoming, we can express it in the actual image shown in Figure 8 and the attachment (the upper left corner of the attached image) That is, the conventional light-emitting diode bulb light and shadow imaging), such as the first light type distribution line (C JL ) of the main brightness and the second light type of the secondary brightness (C2) are all placed on the lamp holder (5 〇 ) Above or near the horizontal line (L〇) of the end face, the periphery of the lampshade (8〇) is actually very dim, resulting in insufficient illumination. Φ is its main disadvantage. 2. Second, as shown in Figure 6. , because the conventional light-emitting diode (7 〇) is a completed packaged part ( Wafer), so it needs to be soldered to the circuit board on the lamp holder (50) by SMT method. 'Because of the large volume and the working space, it is made between each light-emitting diode (7 〇) When the distance (s) is large, when using multiple light-emitting diodes (7 〇), in addition to occupying a large circuit board (60) area, the heat dissipation module is also larger at 201135152. The volume of the product is also more cumbersome as a disadvantage. SUMMARY OF THE INVENTION The main purpose of the present invention is to provide a circuit board at one end of the lamp socket heat dissipation module, and the high power light emitting diode system on the circuit board is set in the circuit by COB (ie, CHIP 〇 NB 〇 ARD). A spheroidal lamp cover is disposed on the illuminating body of the lamp socket heat dissipation module; therefore, when the invention is used, the illuminating diode system is disposed in the C0B (ie, CHIP ON BOARD) mode. On the circuit board, the illumination angle of the light-emitting diode is close to 18 degrees, and the special coating treatment of the inner wall of the spherical lamp cover can make the light emitted by the bulb reach an angle of more than 270 degrees; and on the overall brightness The light of the main illumination can be below the horizontal line of the end face of the lamp holder, so that the illumination of the lower half of the bulb still has excellent illumination, which is a feature of the invention. The design of the present invention is equivalent to the conventional tungsten filament bulb and the radiation-emitting effect of the power-saving bulb by the luminous angle and uniformity of the illumination. However, since the LED bulb is used in this case, the cost and the life are high, and It is more environmentally friendly and brighter and is a major advantage of the present invention. [Embodiment] In order to enable the reviewing committee to clearly understand the contents of the present invention, only the following description is used in conjunction with the drawings, and the following is explained: Referring to Figures 1 and 2, the present invention includes at least: a lamp holder cooling die Group (i 〇), with a circuit board (2 201135152 ◦) at one end, and at least one light-emitting diode (30) on the circuit board (20) (but the figure of the present invention is six The light-emitting diode (30) is provided on the circuit board (20) in a COB (ie, CHIP ON BOARD) manner. Referring to Fig. 5, since the light-emitting diode (3 〇) is disposed on the circuit board (20) in the form of COB (ie, CHIP ON BOARD), the angle of incidence of the light-emitting diode (3 〇) It is almost straight φ connected to the board (20) to spread out, generally up to about 180 degrees of illumination angle (a 1). The lamp holder heat dissipation module (1 〇) shown in the above figures 1 and 2 is for absorbing and conducting the heat generated by the light-emitting diode (3 〇), and is guided to dissipate. A spherical lamp cover (40) is disposed above the light-emitting diode (30) of the lamp socket heat-dissipating module (10), and the inner wall (40°) of the lamp cover (4〇) is a spherical inner surface curvature As shown in the second and third figures, when the light-emitting diode (30) emits strong white light, it can be uniformly emitted toward the inner wall (4〇〇) of the lampshade (40), wherein the emitted light (L1) If a vertical or nearly vertical angle is projected on the inner wall (4〇〇) of the lampshade (40), it will pass through the lampshade (40). If it is too obliquely projected on the inner wall of the lampshade (40) (4 0 〇) When the light (L 2 ) is continuously reflected in the lamp cover (40) until it passes through the lamp cover (4〇), it reaches a full light projection close to the conventional light bulb. In addition, in order to make the light reflection inside the bulb uniform, the lampshade (4 201135152 (the inner wall of η) can be coated with a reflective material that enables the light to be more uniform in brightness. Therefore, the present invention is used. When the light-emitting diode (3〇) of the present invention is provided on the circuit board (2 〇) in the form of c〇b (ie, cmp ON BOARD), as shown in FIGS. 3 and 4, the light-emitting diode is provided. (3 0 ) The angle of illumination is connected to & 18〇", plus the spherical reflection, which enables the inner wall of the lampshade (40) of the bulb (4〇〇

所發出光的角度（Θ)可達270度以上；且於主要 亮度的第一光型分布線（C1)及次級亮度的第二 光型分布線（C2)均落於燈座（50)端面的水 平線（L 〇 )以下，使得燈泡的下半部周遭仍具有 極佳的照明，這點可由本發明附件的實際攝像圖所 證明，該附件裡的右下方所攝像圖即為本發明，該 亮度可以擴及至燈泡的下方周遭；此一照明效能 是等同於附件裡左下方的鎢絲燈泡及右上方的省電 燈泡的輻射狀發光效果，但由於本案係使用LED燈 泡’故成本及壽命均高，且更為環保、明亮，是本 發明的主要優點。 以上所述者，僅為本發明之較佳實施例而已， 並非用以限定本發明實施之範圍，其他如附加各種 習知既有的技術及元件，在不脫離本發明之精神與 範圍下所作之等效取代與修飾，皆應涵蓋於本發明 之專利範圍内。 201135152 【圖式簡單說明】 第1圖 係本發明之部份結構剖視立體圖。 第2圖 係本發明之全剖結構示意圖。 第3圖 係本發明之使用功效示意圖。 第4圖係使用本發明之光型分布位置示意圖。 第5圖係本發明以COB(即CHIP ON BOARD)方式The angle of the emitted light (Θ) can reach 270 degrees or more; and the first light type distribution line (C1) of the main brightness and the second light type distribution line (C2) of the secondary brightness are all dropped on the lamp holder (50). Below the horizontal line (L 〇) of the end face, the lower half of the bulb still has excellent illumination, which can be proved by the actual image of the attachment of the invention, and the lower right image of the attachment is the invention. The brightness can be extended to the lower circumference of the bulb; this lighting performance is equivalent to the radiation effect of the tungsten bulb at the lower left of the accessory and the power-saving bulb at the upper right, but since the LED bulb is used in this case, the cost and life are both High, and more environmentally friendly, bright, is the main advantage of the present invention.
